Unified Bridge
The core interoperability layer enabling seamless cross-chain communication and asset transfers across Agglayer connected chains
Overview
The Unified Bridge is the core interoperability layer that enables seamless cross-chain communication and asset transfers across Agglayer connected chains. It solves the fragmentation problem by providing a unified interface for L1 to L2, L2 to L1, and L2 to L2 transfers.
Key Benefits:
- Unified Experience: Single interface across all connected chains
- Trustless Security: Cryptographic verification of all transactions
- Developer Friendly: Simple APIs and comprehensive tooling
What You Can Do
- Transfer Assets: Bridge tokens and native assets between any connected chains
- Execute Cross-Chain Calls: Trigger smart contract functions on destination chains
- Build Cross-Chain Apps: Create applications that work seamlessly across multiple chains
How It Works
The Unified Bridge uses a sophisticated Merkle tree structure to securely track and verify all cross-chain transactions:
Security Model:
- All transactions are settled on Ethereum before claiming
- Cryptographic proofs verify every cross-chain operation
- Immutable transaction data prevents incorrect claims
